Rosemary oil has the strongest published evidence of any essential oil for hair growth — the Panahi 2015 RCT showed rosemary oil 2x weekly was equivalent to topical 2% minoxidil at 6 months. TikTok and Instagram have driven massive recent demand for rosemary oil + hair growth content. For GLP-1 users with telogen effluvium from semaglutide, tirzepatide, or retatrutide, rosemary oil is a low-cost ($10-$25) addition that stacks naturally with supplements + LLLT.

Frequently Asked Questions
Does rosemary oil actually grow hair?
Yes — the Panahi 2015 RCT showed rosemary oil 2x weekly was equivalent to 2% minoxidil at 6 months in androgenetic alopecia. Modest but real effect. For telogen effluvium from GLP-1, similar mechanism (improved scalp circulation) should apply.
How to use rosemary oil?
2x weekly application. Apply to scalp (not just hair), massage in 2-3 minutes, leave on 30 minutes minimum (or overnight), shampoo out. Continuous use for 4-6 months for visible results.
Do I need a carrier oil?
Pure rosemary essential oil: yes (typically jojoba or castor at 1-3% concentration). Pre-mixed products (Mielle, Briogeo, Handcraft): no — already diluted.
Mielle vs Briogeo — which is better?
Mielle: cheaper ($10), more cult-following, slightly heavier. Briogeo: premium ($25), lighter texture, better for fine hair. Both work; Mielle wins on price-per-bottle.
Safe with GLP-1?
Yes — topical essential oils don't systemically interact with semaglutide, tirzepatide, or retatrutide. Patch-test first if you have sensitive skin.
Can I use rosemary oil with minoxidil?
Yes but stagger them. Rosemary oil 2x weekly (e.g., Tue/Sat). Minoxidil daily on other days. Don't apply both same day — competing absorption.
